Answer:

Food should be stored with spaces in between in the fridge storage compartment. In particular, do not place food near its back wall. When the refrigerator is operating, the surface temperature of the evaporator on the inner wall of the fridge storage compartment is very low and moisture will condense on the back board of it.

Do not place food of high moisture in the fridge storage compartment. If you really need to do so, you'd better to wrap it with a piece of preservative film.

Do not set the temperature too low,uaually,5℃ is More appropriate.

Do not put the food that easily frozen in the bottom,because there is the lowest temperature at the bottom.
